In the autumn of the 19th year of Chengqing, an imperial edict granting marriage pushed Xie Mingshu, the legitimate daughter of the Zhenbei Hou Mansion, into the most dangerous chess game of the Great Jing Dynasty.
She is the only daughter of the Marquis of Zhenbei who has a hundred thousand frontier troops. She has been immersed in military strategies since she was a child. He is the iron-blooded prince Xiao Yu, who is well-known in both the government and the public. He has great military achievements and a sinister temperament. For him, this marriage is just a move to appease the emperor and strengthen his power.
Hongzhuang entered the prince's palace ten miles away, but there was no warmth, only a cold blade hidden in it.
"Stay safe in the backyard, don't ask about foreign affairs, and don't make personal friends." The warning on the wedding night was hardened to every word.
But Xie Mingshu didn't believe in fate. She used meekness as a mask and wisdom as a sharp blade. She worked step by step amid the shackles of the royal palace and the treacherous wind and frost swords in the court. What she wants is never the dignity of a caged bird, but to escape the fate of a chess piece and be the one who plays chess.
The war in the north has not cleared, the undercurrent in the capital is raging, and the drama of the princes competing for the heir apparent has quietly begun. When the concubine of the Hou family confronts the iron-blooded prince, will they check and balance each other, take advantage of each other, or will they develop unexpected bonds through repeated confrontations and tests?
The chess game is open, and there are no regrets for your moves. Let's see her hidden edge in her hairpin, stirring up the wind and clouds in the high wall and deep palace, seeking a life-and-death agreement, and the peace of her family and country.
